The Bents embarked on a ‘fleet’ of ships during their twenty years of explorations to the Mediterranean, Middle East, and Africa, from 1880 to 1900 (see the interactive maps on this site for additional info!).
January/February 1891 saw them on board the ‘Garth Castle’:
“We left England January 30th , that is to say Theodore and Mr. Robert Swan and I, bound for Mashonaland, and Mr. Graham who was going to accompany us as far as Kimberley. The ‘Garth Castle’ was a comfortable ship and with no adventures we reached Cape Town Thursday, February 19th.”
The Bents took about three weeks (30 Jan – 19 Feb 1891) to steam, with stops, from the Channel to Cape Town. The ‘Garth Castle’ (1) was built in 1880 by John Elder & Co. at Glasgow “with a tonnage of 3537grt, a length of 365ft, a beam of 43ft 6in and a service speed of 12 knots”. She took the name of fleet-owner Sir Donald Currie’s estate in Scotland. She was transferred to the Intermediate service in 1890 at the time of the Bents’ trip to Cape Town in 1890/1, under Master H. H. Broadfoot. Surplus to requirements when the companies she was linked to merged in March 1900, she was sold to Elder Dempster & Co. in 1901 for their Bristol to Jamaica service and in the July of the same year chartered to Franco-Canadian Steam Navigation Co. for their Dunkirk – Bordeaux – Quebec run. 1902 saw her being was sold on again, to the Khedivial Mail Steamship & Graving Dock Co. of London, renamed the ‘Ismailia’. She was sold on to Soc. Armatrice Radivo-Frausin of Trieste, renamed, alas, the ‘Brunette’ and broken up in Italy in 1923.
